I saw two Downy Woodpeckers showing territorial display behavior in the woods. I wasn't able to catch a photo of both of them in action, but it was still fun to watch it. Basically, one would get too near the other, and this was followed by wing flapping, tail spreading, bill pointing and general scuffling. One would fly off, and the other would chase it, and they would start again. They took some time out to peck at separate trees, and then they joined in their confrontational behavior again.
